Signal Ground VS Chassis Ground
The power ground is mainly for the path of the power loop current. Generally speaking, the current flowing through the power ground is relatively large,
Switching Power Supply: Uses Advantages and Working
A power supply is an electrical device that converts the electric current that comes from a power source to the voltage value necessary for powering a load, like a motor or an electronic device.
How do you measure input and output impedance?
Input resistance is a measure of the amplifier’s effect on the signal source. The larger the input resistance, the smaller the current taken by the amplifier from the signal source, and the larger the signal voltage obtained at the input terminal of the amplifier,
Tips and PCB Design Guidelines for EMI & EMC
The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to be stronger and stronger, so PCB design has become more difficult
PCB Testing Methods Guide sharing
Before explaining the inspection work after the PCB wiring is completed, I will introduce three special wiring techniques for PCB. The routing of PCB LAYOUT will be explained from three aspects: right-angle routing, differential routing, and serpentine routing.Today author from QiHe smt pick and place machine discussing about it with you . Right-angle routing (three […]
Introduction to Microcontrollers
The selection of single-chip microcomputer is an important and troublesome thing. If the type is selected properly, the product will be cost-effective and work stably; otherwise, it may cause excessive product cost or affect the normal operation of the product, and may even fail to meet the pre-design requirements at all.
How to reduce PCB Design errors and increase efficiency
PCB circuit board design is a critical and time-consuming task, and any problems require engineers to check the entire design network by network and component by component.
How to strengthen anti-interference ability in PCB design
Printed circuit boards (PCBs) are the supporting components for circuit components and devices in electronic products. It provides electrical connections between circuit components and devices. With the rapid development of electronic technology, the density of PCBs is getting higher and higher.
Electrical Symbols for Electronic Components
n pcb circuit diagrams, graphical symbols identify network components and devices. International letter symbolism is based on the Roman and Greek alphabets. Qihe SMT Line Equipment today will share with you some common symbols and their meanings .
